新课程实施以来,学生自主探究的机会越来越多,有些教师对其后的反馈环节缺乏重视,往往请个别学生汇报结果后就匆匆收场。其实反馈是探究活动后的重要环节,正如控制论创始人维纳所说:“一个有效的行为必须通过某种反馈过程来取得信息,从而了解目的是否已经达到。”有效的反馈是探究活动的“点睛之笔”。 Since the implementation of the new curriculum, students have more and more opportunities for self-exploration. Some teachers lacks emphasis on the feedback links that follow and tends to hurry after individual students report the results. In fact, feedback is an important part of the exploration activities, as Wiener, the founder of cybernetic theory, said: “An effective act must obtain information through some kind of feedback process so as to know whether the goal has been achieved.” Effective feedback is to explore Activities “finishing touch ”.
